NSW Physiography Category: Landform Features in GDA2020

Spatial Services (DCS) provides a geospatial dataset representing topographic landform features across New South Wales, Australia. The dataset includes lines, points, and polygons for classes such as Distinctive Land Surface and Fuzzy Extent features like dunes, plains, and cliffs. It was updated to the GDA2020 coordinate reference system on 2026-05-17 to align with the national standard.

Use Cases

• Classifying landforms such as intertidal flats and reefs based on the Distinctive Land Surface feature classes.
• Mapping approximate locations of indistinct named landforms like dunes and valleys using the Fuzzy Extent categories.
• Integrating topographic feature data with other spatial layers using the modern GDA2020 coordinate system.

Strengths

• Updated to the GDA2020 coordinate reference system, improving accuracy and national compatibility.
• Description lists specific feature classes such as DLSArea, DLSLine, and multiple FuzzyExtent categories.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
